Abstract:
The experiment was carried out on fifteen lactating cross-bred cows (Tharparkar/Sahiwal x HF) to study the effect of different feed supplements on economics of milk production at dairy farm of S.K.N. College of Agriculture, Jobner (Rajasthan). The animals were subjected to three dietary supplements i.e., concentrate mixture (T₁), concentrate mixture + UMMB (T₂) and concentrate mixture + Azolla (T₃). The average milk production (litre/cow) during study period was significantly higher (P<0.05) in T₂ (7.54) as compared to T₃ (7.27) and T₁ (7.13). Highest B:C was found in T₂ group (3.01) compared to T₃ group (1.82) considering only the benefits of milk production. The average daily feed cost per L milk production was Rs. 26.29, Rs. 25.23 and Rs. 26.06 in T₁, T₂ and T₃ groups, respectively. The supplementation of UMMB was more beneficial as compared to other groups.
